Christoph, /proc/slabinfo is an _ABI_. You HAVE to provide it. slabtop
relies on it, people use it every day to monitor memory consumption.
I'm really getting worried that you are apparently incapable of grasping
such _SIMPLE_ concepts. Who the heck cares whether you put in zeros or
whatever else in some of the fields? People use it to know how many
objects are allocated and sure SLUB knows that count, sheesh. How on
earth can you come up with a lame excuse like that? You dont like the
'SLAB' portion of the name perhaps? Is it NIH again?
Really, if your behavior is representative of how our SLAB allocator
will be maintained in the future then i'm very, very worried :-( You
ignore and downplay clear-cut regressions, you insult and attack
testers, you are incredibly stupid about user ABIs (or pretend to be so)
and you distort and mislead all the way. What will you be able to do in
the much less clear-cut cases??
